PA, I was thinking that of the procedure is in the box, it must have been approved somewhere along the way....the operator would know if their OpSpec and training allow them to use it.
I have noted there is confusion with these types of overlays, that many people feel that the VOR or other navaid must be operational, as it is shown on the plate, but that can be mistake.
I know of wuite a few RNP AR procedures where one of the waypoints on final is a VOR or NDB, but that is simply using the waypoint in the database, not an operational navaid.
Some RNP AR procedures use the navaid as one of the entry points, but again, it doesnt need to be operational.
Would really have to see specifics...
